Auto-expand text input height?

I had neglected to include capital letters… oops! This version has them and I’ve also modified the blocks to be a bit more efficient and dynamic and not to rely on static values as much.

Punctuation is returning a NaN value and resetting the calculated height of the text input. I know the comma (,) is a problem due to the fact that I’m using csv lists. Just not sure what to do about that. I guess I should use a different delimiter.
